Re: LCD monitor went haywire

I dont know how you found this site - have you read ANY threads regarding monitors.
You dont even tell us the monitor model number!
Have you tried anything except switching it off and on?

Re: LCD monitor went haywire

When it says 'NO SIGNAL' that means the PC is not putting out the video to the monitor or the viodeo input at the monitor is bad, you can try your monitor with another PC, or another monitor with this PC.

"What is the problem? The motherboard? Graphics adaptor? LCD?" + Bad cables or cables are not seated properly? It can be any of those that is why process of elimination troubleshooting is required.

Someone told me to post my problem on this site; and provided the link.

The model # is AOC 2217V.

Everything is working fine now. The problem is sporadic. So I didn't try switching monitors.

Re: LCD monitor went haywire

Ok - I would just warn that if the problem is not cable related and is capacitor related
what is now sporadic will get worse and may create an even bigger problem in future as when a cap is deteriorating it is putting pressure on other more expensive and difficult to replace components.

First can you try another screen on your PC to establish it is not the PC/video card that is a problem.
If you dont have another screen then remove cleand and reseat your video card.
Remove and reseat the monitor lead VGA? HDMI? etc
Have you another lead you can connect the monitor to the PC with.
Have you another PC or Laptop you can connect the monitor to.

If none of that helps We can usually help a lot more if you post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

Please do not post inline and offsite as they slow down the loading of pages.

Re: LCD monitor went haywire

I have a laptop that is connected to an external Smasung LCD 933bw; so I switch the 2 monitors -- by changing the connectors at the computer end (if it makes any difference). Both boot up fine. But since the problem is sporadic, does this prove anything?

I don't think this is related, but just in case....

After I switch back the LCDs to the original computers; I try to run a backup of my PC to a Seagate external HD -- with Seagate's BounceBack program. The PC crashed with that Blue screen while scanning the source drive. I ran it again, and the same thing happened. I have ran that program before with no problems. As I said, this may be unrelated.

My computer knowledge is basically at the user level. I can change/add HD, RAM, other adaptor cards. That's about it. I have no idea what a capacitator is and have not done any soldering (don't even have a soldering device).

With respect to "Have you another lead you can connect the monitor to the PC with."; do you mean another video cable? If not, what do you mean by "lead".

With respect to "...what is now sporadic will get worse and may create an even bigger problem in future as when a cap is deteriorating it is putting pressure on other more expensive and difficult to replace components.", what expensive components are you referring to?

This Dell Dimension 2400 is 7-10 years old? Unless it is something simple that I can handle, it is probably not worth paying someone to fix it.

Still, I would like to know, if possible, whether the problem is on the PC side; or the LCD.

Someone suggested that I stress test my PC with SiSoftware's Sandra. I downloaded Sandra Lite 2012; but for something reason, I couldn't get the stress test to run. All I manage to get is the benchmarks; and analysis of the various components.

The Benchmark was "finished successfully" except the following - video related:

Just to get it clear are you saying your normal set up is a PC with the AOC
monitor and a laptop with the Samsung monitor.

If so can you run the PC with the Samsung and the laptop with AOC over the time period the fault would normally present. That would verify if the fault was with the monitor or the PC.
What is sporadic, once a day/week/ month?

I don't think this is related, but just in case....

Hardly relevant if you have no idea what a capacitor is, however I was thinking of mosfets, transformers, diodes and bridge rectifier.

Did you clean and reseat the video card - maybe also update the drivers.

If you cut and paste bits out of the warning eg 0x0000007E and fastfat.sys into google then you may find out what the fault relates to.

A quick look suggests reseating ram video cards and other peripherals updating drivers and so on - even suggests that fastfat.sys may be corrupt or
even the one running may be a virus.
So Id suggest run a virus scan, reseat ram and video card and check hard disk data cable is plugged firmly at both ends.

Re: LCD monitor went haywire

You are correct in the set up of my 2 computers.

In the last month or so, it happened twice. 1st time the screen went black shortly after the PC is powered on and I was away from my PC; and I couldn't "wake up" the screen. 2nd time, the screen "went haywire" at power on. Both times, when I power off my PC and turn it back on after 30 minutes, everything is fine. I don't know whether everything would be fine if I turn it back on after 30 seconds.

I think I have another VGA cable. But I guess there is no point trying that cable unless I have another episode of this problem.

I think I have the latest driver for the video card. Nvidia's driver search is not currently working. I'll have to look there again.

I have 2 copies of fastfat.sys on my PC; I scan them with Norton AV; and they are clean. The files size also conforms to one of the sizes listed as being real files.

I will run a full diagnostic on my HD.

Re: LCD monitor went haywire

Can you open the computer and inspect the video card ? Does it have a fan ? Is it running ok ? Also, observe if the capacitors in it are bulging. If you aren´t sure, post good pictures of the card here so somebody can advise .

I ran SeaTools for DOS' Long test twice. Passed both times.

I am wondering. Since the Blue Screen happened when I tried to run the Backup software to the external [USB] drive; is there a free diagnostic software that I can use to test that external drive?

They seem to be ok. Well, like the others said : exchange the monitors between machines, and give them time to have the problem ( or not ) . If it is something with the pc, it will happen with the second display as well
